1、修改主机名称 （修改主机名永久生效）  
\[root@localhost ~\]\# hostnamectl set-hostname OA-TS-DB-test  
\[root@OA-TS-DB-test ~\]\# hostname  
OA-TS-DB-test

\[root@OA-TS-DB-test ~\]\# uname -a  
Linux instance-y514l7ol 3.10.0-693.11.1.el7.x86\_64 \#1 SMP Mon Dec 4 23:52:40 UTC 2017 x86\_64 x86\_64 x86\_64 GNU/Linux

\#\#这里注意内核的版本信息

2、上传mysql-5.7.13-1.el7.x86\_64.rpm-bundle.tar>mysql-5.7.13-1. el7.x86\_64.rpm-bundle.tar 文件并解压  
\[root@OA-TS-DB-test src\]\# rpm -ivh --nodeps --force mysql-community-common-5.7.13-1.el7.x86\_64.rpm  
\[root@OA-TS-DB-test src\]\# rpm -ivh --nodeps --force mysql-community-libs-5.7.13-1.el7.x86\_64.rpm  
\[root@OA-TS-DB-test src\]\# rpm -ivh --nodeps --force mysql-community-client-5.7.13-1.el7.x86\_64.rpm  
\[root@OA-TS-DB-test src\]\# rpm -ivh --nodeps --force mysql-community-server-5.7.13-1.el7.x86\_64.rpm  
  
3、创建MySQL自定义MySQL 目录文件  
\[root@OA-TS-DB-test src\]\# mkdir /data/mysqldata/data3306 -p  
\[root@OA-TS-DB-test src\]\# chown -R mysql.mysql /data/mysqldata/data3306/  
  
4、配置my.cnf 配置文件  
\[root@OA-TS-DB-test src\]\#  cat << EOF > /etc/my.cnf  
\[client\]  
port = 3306  
socket = /tmp/mysql.sock  
default-character-set = utf8

EOF

5、MySQL 数据库初始化（不推荐）  
第一种：生成密码  cat /var/log/mysqld.log    \#\#竟然没有密码，好奇怪~~  
mysqld --initialize --user=mysql  
  
第二种：没有密码（推荐）  
mysqld --initialize-insecure --user=mysql

6、启动MySQL服务如出现报错，

systemctl start mysqld

mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such f  
  
解决方法：  
\[root@OA-TS-DB-test src\]\#  yum install -y libaio  
  
7、登录MySQL 5.7.13  
\[root@OA-TS-DB-test data3306\]\# mysql -uroot -p  
Enter password:
